SON, a citizen of the United States, residing I have heretofore, as disclosed by my Pat-, at San Jose, in the county of Santa Clara ent No. 1,402,193, dated January 3, 1922,

Y 8 and State of California., have invented cersoughtto remedy these ditficultiesby so distain new and useful Improvements in Matorting 4the'wall of the receptacle' from its 60 chilies for Treating Canned Goods; and I circularity as to form an underlying troughrdo hereby declare that the following is a like drain chamber opening directlyin the' full, clear, and exact descriptionthereof, interior of the receptacle, and having the 10 reference being had to the accompanying coils of the helical rai'lbridge the opening.

Examples of these the` receptaclein which the' fixed rail is dismachines are those'known as cookers in POSGCl' dleCtly aglllSt fS Wall, may be rigwhch the canned goeds are heet-treated; idly crcumferentially continuous and still 3o and those called coolers. in which the premay be fully drained, and may also have a 1 viously cooked canned goods are subjected SPRCG 0?

In Amachines of this type,`the common With those ends in view, my invention practice has been to carry the iixed helically consists in the novel machine or apparatus directed rail-memberof the can-track, upon for treating Canned goods, which I shall va series of longitudinal stringere supported 110W- fully describe by reference'to the ac- 9e in the receptacle and spaced from its walls. Companying drawings, In which I have found, however, that a simpler e011- Figure lA is'a longitudinal, broken section struction is to bolt orv rivet said rail member of my improved machine or apparatus.

But l is the receptacle of the machine, circular this presents a difficulty of draining the re-t in cross sec-tion and provided with an inlet ceptacleof the ltreating liquid, namely the indicated'at 2 in Figure 1, and an exit., in-

A water used therein, since Vportion ofthe dicated at 3, for the canned goods which water will remain in -the bottom between pass through it. 100 the coils ofthe helical-rail'if bolted directly l/Vithn the receptacle and bolted or against the receptacle wall, and will not riveted directly to and against its Wallis drain out. Also, especially in the case of the fixed rail 4. This rail, which is prefercookers, which require the inclusion withinl ably of T-section4 with its leg portion eX- thereceptacle of a steam-pipe for heating tending inwardly is helically directed 105 the water, the disposition of the helical rail throughout substantially the'length of the l directly a ainst the receptacle wall, leaves receptacle, and forms one member of the no room for the steam pipe, which must, can-track. The other member of said track a driving shaft 7..

Below the receptacle l is a longitudinally extending .header pipe 8, into one end of which is fitted an inlet water pipe 9, and

wardly from pipes 11, entering the receptacle bottom, each at a point between the coils'of the fixed helix rail 4.

It will now be seen' that, notwithstanding the disposition of the rail 4 directly against the receptacle wall, all the treating water within the receptacle may be drained out as occasion requires.

Inthe caseof a cooker, where a source of heat mustl be provided, the header pipe 8 and drain pipes ll being outside of the fixed rail 4, serves as a means for introducing and housing a steam pipe 12.

In this improved construction, it will be seen that the circularl receptacle'fis unbroken and may be made as capable of resisting internal pressure as the circumstances require, andstill it may be fully drained and convenient provision made for introducing steam.
